What dafuk is dat resolution. Unless you have chicken eye and see 2way at the same time that thing is soo wrong . My opinion. Buy a third 1080p and make a eyefinity(now youre just doing it wrong) . Then buy a r9 290x with aftermarket cooler(saphire toxic with the 3yellow vents looks great ) or a 780ti. Or wait for gtx880(ti):
880(ti).Reasons to wait and buy it:
-it will be on 20nm
-it will powerfull
-it will have humongonous improvements in the performance/watt sector(see the gtx750(ti) which still is on 28nm but has performance over r7 260x at almost half energy and doesnt needs pci-e connectors at all)
-it will be cheaper ( it its right. Release price will be lower than the one of 780(ti))
-as for the bus width even though its was rumored to be 512-bit it may be 256 ( from last sources).
